Patent DE-3634061-A1 (DE)
Title: Universal multi-purpose lift for travelling mainly vertically, encircling sectional girders of different cross-sections
Inventor: WENKER LUDWIG
IPC: B66B9/187
Filed: 1986-10-07
Abstract: In order to climb scaffolding, steel beams, and cylindrical or tapered pipes, such aids as grapplers, ladders and the like have been used until now. In order to negotiate such heights more easily and conveniently, a powered transportable universal multi-purpose lift has been developed. This lift can run along sectional girders vertically without difficulty, under motor power and utilising the frictional grip. Wheels, rollers, or conveyor chains fitted with elastic contact surfaces serve as the power transmission. In order to counteract unintentional reverse running, and thus the danger of a crash, a rollback lock is built in. When used on tapered girders, a simple mechanism compensates automatically for the different cross-sections. One of the advantages of the universal multi-purpose lift is its mobile use in difficult terrain. Both people and loads can be transported.

Title: Aggregates for prewetting and/or dispersing in the field of preparing printing pastes and printing inks
Inventor: KAISER WILLI DR
IPC: C09D17/00
Filed: 1986-11-03
Abstract: The invention relates to aggregates for prewetting and/or dispersing pigments in highly viscous and liquid materials to be ground, such as are usual in the printing inks, coatings, paints and related industries. For occupational health reasons and/or medical reasons, the pigment-processing industry increasingly demands pigments which do not evolve dust. In the simplest way, this problem is solved by the use of granulated pigments. According to the invention, an aggregate for predispersing on the one hand and an aggregate for dispersing granulated pigments on the other hand in highly viscous binders are proposed. The aggregate according to the invention for predispersing consists of a comminuting apparatus in the nature of a turbine-driven mechanism with stationary and moving blades arranged in a housing, the blades interacting by more or less intensive contact. For the actual dispersing, the device is proposed which consists of a housing with a roller designed as a conveyor screw, the flank area of the screw threads being preferably large (Fig. 1). <IMAGE>

Title: Apparatus for destroying data on a data tape
IPC: B41J35/38
Filed: 1987-01-24
Abstract: In order to destroy the data on a data tape, or at least make it impossible to remove the data from the tape, the tape is introduced, if appropriate with an associated cassette, into the container (1) of the apparatus and heated to a predetermined temperature for a sufficient period of time. The container (1) can be closed by means of a hinged cover (2), in order to avoid unintentional touching of the cassette heated to a high temperature. To prevent the latter, but also to prevent undesired access to the cassette before the "destroying" of the data on it, there is also provided a temperature-dependent blocking device (36), which allows opening of the cover only after the temperature has dropped into the range of room temperature. The rapid cooling is accomplished by a fan (42) together with cooling ribs (46) on the tray (3) receiving the cassette (4). The heating of the cassette is controlled in a preferred way by means of the on-time of the heating device (6) operating at full power. A timer (47) is installed for this purpose. <IMAGE>

Patent DE-3709499-A1 (DE)
Title: Capacitor
Inventor: KLASCHKA RUDOLF
IPC: H01G4/224
Filed: 1987-03-23
Abstract: The capacitor, expecially a cup-type capacitor having very small dimensions, in consequence has improved cathode contact between the capacitive element and the electrically conductive housing, especially an aluminium housing, in that the cathode contacts are made by means of a contact disc which has on its radial outer edge microribs which run axially and parallel to one another and merge into blade-like edges radially on the outside. As a result of conical construction of the interior of the cup-type housing, by means of knurling or beads, or by spreading of the disc, the cathode connecting elements (generally tabs) are then pressed by means of the microribs into the housing wall such that they are stamped in and cold welded, not only an electrically highly conductive connection but also a mechanically firm connection being obtained between the cathode connecting tab and the housing.

Inventor: SCHIMMEL GUENTHER DIPL CHEM DR
IPC: C01B33/38
Filed: 1987-06-01
Abstract: Crystalline sodium silicates having a layered structure and a molar SiO2:Na2O ratio of 1.9:1 to 3.5:1 are prepared from water glass solutions having a solids content of 20 to 65 % by weight by first treating the water glass solutions in a spray-drying zone. This gives a pulverulent amorphous sodium silicate having a maximum loss on ignition of 20 % by weight, while the waste gas leaving the spray drying zone has a temperature of at least 140 DEG C. The spray-dried sodium silicate is then heat treated in an ignition zone having a movable solid bed at temperatures of 500 to 800 DEG C for 1 to 60 minutes in the presence of at least 10 percent by weight of recycled material. This recycled material was obtained by mechanical comminution of crystalline sodium silicate discharged from the ignition zone.

Patent DE-3810162-A1 (DE)
Title: Hydrostatic torque converter executing circulatory translation
Inventor: ARNDT FRANZ MARTIN
IPC: F16H39/18
Filed: 1988-03-25
Abstract: Hydrostatic torque converters according to the invention, which execute circular translation and in which the cylindrical rolling-contact wheels have a frictional torque controlled by the load torque and dependent on the delivery volume of the hydraulic pump, act by slip between these wheels as a starting or safety clutch or by stiction during rolling contact as single-stage torsionally rigid torque converters with a high conversion ratio which disengage without slip when the hydrostatic pressure is removed. Efficiency during rolling contact with stiction is high because of the small elastic deformation of the rolling-contact surfaces despite the high contact pressure. The driving power of the hydraulic pump is very low relative to the maximum transmission capacity. For the purpose of dynamic mass balancing and hydrostatic balancing of forces, three rolling-contact wheels offset by 180@ are proposed. The amount of noise developed is lower than in the case of torque converters which employ gearwheels. Suitable materials for the rolling-contact wheels are: hardened and tempered steel, cast steel, spheroidal graphite cast iron, bronze, plastic, ceramics, brake-lining material. Rolling-contact wheels run dry or lubricated depending on the intended use and the materials employed.
